Where in the hair structure is nourishment supplied?

Hair shaft
Hair follicle
Hair papilla
Hair bulb

The correct answer is: Hair papilla

Nourishment for hair is supplied through the hair papilla, which is a small, bulb-like structure located at the base of the hair follicle. The hair papilla contains blood vessels that provide essential nutrients and oxygen necessary for hair growth. It is connected to the hair bulb, where new hair cells are generated. The hair follicle encases the hair bulb and papilla and serves to protect the hair strand as it grows. While the hair shaft is the visible part of the hair, it does not receive any nourishment since it is composed mainly of dead keratinized cells. Thus, understanding the role of the hair papilla is crucial for recognizing its foundational importance in the hair growth cycle and overall health of the hair.
